After looking at some ballistic charts I think 50 yards zero should be good for me. Looks like it will shoot fairly flat (under an inch) out to 135ish then drop to 1.5" at 150y and then its 6.7" at 200.
I did a quick sight in at 75 yards, then plinked with it some this summer. Now that deer season is a few weeks away, it's time to get serious on getting a zero. I also just ordered a sling mount....
Here is the obligatory pic.
